Most apps say "Weak at Algebra."
We say "Weak at factoring."
Knowing you're weak at "Algebra" is useless. Knowing you score 21% on factoring quadratics — and 91% on linear equations — tells you exactly what to do next.
Praczo tracks mastery across all 183 SAT concepts and lets you drill any concept with a single tap. Your study time goes to exactly where it's needed.

The scores speak for themselves
“I'd been studying for months and plateaued at 1340. Praczo showed me I was losing almost all my points on two specific grammar concepts. Two weeks of drilling those and I jumped 180 points on the real test.”

“Other apps just said I was weak in "Math." Praczo told me I was weak at setting up equations from word problems and interpreting scatterplots. That specificity is what actually fixed my score.”

“The AI tutor is genuinely incredible. I asked it to explain the same concept five different ways until it clicked. My math teacher never had that kind of patience. Worth every penny.”
